Products I build, tools I open-source, and the platform work underneath.
Product · Kotlin Multiplatform · Ktor
A calm companion for people going through lab tests: a test encyclopedia, preparation guides, a private results archive and medication reminders. Live on Cafe Bazaar. I lead product and engineering — app, backend, admin panel and infrastructure.
Open source · Kotlin Script
Kotlin Script tools that find unused resources and dead Kotlin/Java code. On the open-source Unstoppable Wallet they flagged 17 unused resources and 66 likely-unused declarations.
Open source · Jetpack Compose · Web3
A non-custodial Ethereum wallet. BIP-32/44 key derivation is implemented by hand with Bouncy Castle; private keys are encrypted with keys held in the Android Keystore.
Android framework · System apps
Standalone Gradle builds that take AOSP system apps out of the platform tree so they can be built, debugged and studied in Android Studio — plus samples built on Settings search and custom ROM builds. The platform knowledge behind my app work.
